Continuously variable-rigidity chaos vibration isolation device

The invention discloses a continuously variable-rigidity chaos vibration isolation device. The device is characterized in that: the continuously variable-rigidity chaos vibration isolation device comprises a first vibration isolator and a second vibration isolator; one end face of the first vibration isolator and one end face of the second vibration isolator are oppositely arranged; a spacing distance for containing a vibration isolated device is arranged between the first vibration isolator and the second vibration isolator; both the first vibration isolator and the second vibration isolator are contacted with the vibration isolated device; the other end face of the first vibration isolator is provided with a contact surface connected with a base body, and a separated area is arranged between the contact surface and the base body; and the other end face of the second vibration isolator is provided with a contact surface connected with the base body, and a separated area is arranged between the contact surface and the base body. The invention has the advantages that the device can enter into chaos under the small displacement vibration condition, has excellent vibration isolation effect and changes line spectrum into wide spectrum.
